rElie embodimentI selected for illustration discloses the manner of handling the trucks which are filled in the vert-ical conveyer illustrated in my copending application, Serrial No. 426,525. vfiled February 7, 1930. The trucks filled in the vertical conveyer' A are removed therefrom by the conveyer G by which they are transferred to a conveyer` H. The ccnveyer H is reversible and distributes the truck either to the conveyer I or to the conveyer J. Connected to the conveyer I are a plurality of branch conveyers Ktowhich the trucks are delivered through the mechanisni about to be described.

the articles to be handled are divided Thetruck 80v illustrated in Fig. l is substantially rrectangular in form and is provided at the upper end of each end wall with bars 90 having'perforations 91 therein adapted to receive one or more pins 92. It will be noted that the bars 90 extend from one side only of the truck. Referring to Fig. 't it will be obvious, therefore, that when the truck is travelling to the right the bars 90 extend from the right side wall of the truck While when the truck is travelling to the left, the bars 90 extend from the left side of the truck. It will further be noted that in the Apresent embodiment each bar 90 of the truck is provided with nine perforations; perforation 93 is'located: along the central line of the truck' so that there are lseven-holes on one side of the center line and one hole on the other side. The various :operations aboutto be described'are controlled by the position ofthe pin or pins 92 in the forward end of the truck. f v

' .The direction control for the conveyer-'H whichl is rst actuated by the pin or pins 4includes a frame 100 extending over the conveyer G and from which depends pairs of tab platesV 101. 102. VBy referring to Fig. 2 it will be noted that the tab platesy 101` are aligned and separated from each other so that any pin in the perforation 93 of the truck will have noetfect whatsoever. `Each tab platey 101 is associated with two circuit control devices rigidly secured to the frame 100 and is pivotally supported thereby.

hus one tab plate 101is associated with circuit breakers 103 and 104, while the other tab plate is associated withcircuit breakers 105 and 106. vItwill be-understood that Vwhen a tab plate isv struck by'a pin in a passing truck, the circuits' controlled by the two circuit breakers' associated with the particular tab Vplate will be broken. The tab `plates`102 are similar in all respects to the tab plates 101, but the circuit control devices associated therewith are circuit makers 107 and 108 and 109 and 110 respectively. The particular construction of the circuitV control devices forms no part of the present invention and hence is not shown or described. In accordance with the usual well known practice, however, the

devices are tripped when the tab plates are struck and swungby the pins on the trucks. It is `enough here to say that circuits are broken when the plates 101 are swung and that circuitsare made when the plates 102 are swung.

veyer H is accordingly controlledby a re.l

versing switch 122.

The switch 122 niay be of any desiredltype and I have therefore elected'to show it diagrammatically as a magnetic switch comprising coils 125 and 126 which control switches 12'? and y123 respectively. rIhe switch is of the usual type wherein during the energizing of one coil and the consequent closing of the switches controlled thereby, the closing of the switches controlled by the other coil will be prevented if such coil is later energized.l Referring to Fig. 6 it will be noted that circuits 140 and 141 eachV lead to Vcoi-l 125 while circuits 142 and 143 each lead tok coil 126. The circuit 140 includes circuit breakers 104 and .105 in parallel and the circuit 141 includes circuit makers 107 and 110 in parallel. The circuit 142 includes circuit breakers 103 and 106 in series and the circuit 143 includes circuit makers 108and 109 in series. HenceA the circuit 140 will only be opened and the cir'- 'cuit 143 will only be closed when both tab plates 101 and both tab plates 102 are swung whereas circuit 141 will be closed and circuit 142 will be opened when .either of theftab plates 101 and the tab plate 102 beyond it are swung. c

Let us assume that the switch 122 is set so th at the conveyer H is travelling` toward the conveyer I in which case the coil 125 of the switch isV in control. If the truck approaching the tab plates 101 has a pin in any one of the seven holes at the right of the center line-and no pin in the ninth hole it will engage and swingrthe right hand tab plates 101, 102 only (see Fig-2). Thereupon the circuit breakers dand 106 will have no effecten the circuit but will open the circuit 142 while the circuit makers 109 and 110 vwill close the-circuit 141 but` will have no effect the circuit 143. Similar results will follow if the truck has a pin in the ninth hole and none in the rst seven. When, however, the truck has pi ns in any one of the lirst seven holes and also in the ninth hole all the tab plates 101 and 102 will be swung. Under such conditions the circuit 140 as well as the 'circuit 142 willbe opened and later the circuits 141 and 143 will both be closed. The circuit makers are so adjusted, however, that the makers 108 and 109 will act in advance of the makers 107 and 110 and consequently the conveyer which has been brought to rest by deenergizing the coil 125 will be caused to travel toward the conveyer J under the influence of the coil 126.

Then the coil 126 is energized the next truck 80 to approach the direction control will deenergize the coil 126 and stop the conveyer H `regardless of which holes other than the eighth hole are provided with pins 92. If the truck has pins in any of the first seven holes only or a pin in the ninth hole only the :coil 125 will be energized and the conveyer H start traveling toward the conveyer I. If thetruck should have pins in any of the `first seven holes and also in the ninth hole the coil -126 will bereenerg'ized and the conveyor' H will resume its traveling toward the conveyer J. Y

It will be understood thatthe trucks are so spaced and the direction control so located with reference to the conveyer H that the truck actuating the direction control'is delivered by the conveyerl H to the conveyers I or J before the succeeding truck actuates the .control. The trucks having pins 92 at both sides of the center line are deliveredY to the con- -veyer J and transported to a desired destination. The trucks delivered to the conveyer I are further handled as will be now set forth.

The trucks transferred by the conveyer l' to the conveyer I travel along such conveyer in the usuallrnanner. Extending-from one side of the conveyer I areV a plurality of branch conveyers K and associated with each branch conveyer K isa deilectorl@ which is suitably mounted upon a shaft 151 and caused to operate bya motor 152. The shaft V151 is mounted in suitable bearings and carries a deflector bar 153 which is adapted to extend over the belt 154 of the conveyer I. A suitable brace 155 is provided to hold vthe deliector bar 15.3 in the horizontal position.`

The motor 152 is mounted upon a support at one'side of the conveyer I and actuates,

through suitable gearings7 a shaft 156 on which is supported a crank arin 157 having at one end a pivotal connection with one end of a bar 158 pivotally attached at its other end to the deflector bar 153. It will be under# stood that the rotation of the shaft 156 which follows the direction indicated by the arrow 159 causes the deilector bar 153 to be ad; vanced into the deiiecting position as shown in dotted lines in Fig. 11, or retracted to the inoperative position shown in full lines in that ligure.

Mounted adjacent the shaft 156 are a pair f of circuit breakers 160 and 161. These cir- .cuit breakers are of the usual type having of the circuit breaker 161. starterl 165 will not be energized and the dethe crank arm 157 as the shaft is rotated. The trips 162 and 163 of the circuit breakers 160 and 161 extend into the path of the arm 164 as the shaft is rotated andare actuated thereby. The motor 150 is driven by an automatic starter 165 shown diagrammatically in Fig. 14 and which may be of any desired type. Y

Associated with each deiector is a control device which is engaged by the pins on the trucks transferred by the conveyer l. This device comprises a frame 170 extending over the belt 154 of the conveyer I from which depends a tab bar 171 and a tab 172 as shown particularly in Figs. 9 and 10. The tab bar 171 is pivotally mounted and provided with a notch 173 through which a suitably located pin on a truck will pass freely. It will be understood `that if the truck carries any pins 92 which are not so located that they pass freely through the notch 17 3, the tab bar 171 will be swung relative to the frame 17 0. FiXed upon a bracket 174 is a circuit maker 17 5 from which one end of the bar 171 is supported. The other end of the bar is supported by a bracket 176. A second circuit maker 177 is supported on abracket 17 8 behind the brackets 174 and 176. rIhe tab 172 is pivotally swung from the circuit maker rEhe circuit makers 17 5 and 177 are similar to the circuit makers and circuit breakers which are elements of the direction control previously described and the swinging of the tab bar 171 or the tab 172 trips the circuit makers by which they are carried. The tab 172 is directly behind the notch 173 in the tab bar 171 and will therefore beengaged and swung by the pinon any truck which passes through the notch.

Referring to Fig. 14 it will be notedthat the circuit maker 17 5 and thecircuit breaker 16() are in series in a circuit 180 leading to the automatic starter 165 and that the kcircuit maker 177 and the circuit breaker 161 are 1n series .m a circuit 181A also leading to the automatic starter 165. The Aarm 164 however, when the defiector is at rest, is in functioning engagement with one of thefcircuit breakers. 1f the deflector is open as shown in full lines on 11, the circuit breaker 160 is tripped and the circuit 130 is open while if the detlector is closed, as shown in dotted lines on 11, the circuit breaker 161 is tripped andthe circuit 181 is open.

Assume that the deflector is in the open position in which case the circuit breaker 160 is closed and the circuit breaker 161 is open. lf the truck approaching t-he control device .has its pin so located that it will not pass through the notch 173 but will trip the tab bar 171 the circuit 181 will not be closed by the circuitmaker 17 7 due to the position Consequently the t will of course, be understood-that the notch 173 in each tab bar 171 together with the tab 172, will vary in location so that a pin may be set on a truck to insure its delivery to Yany desired/branch conveyer K. Since the eighth holein the bar 9() is'employed as pointed out `in my copendinglapplication for a certain purpose there willy be no tab and notch for such location of thel pin. r1`he pin, in the eighth hole of the bar atthe forward end of a truck will engage .the tab bar 171 of veach deflecto-r mechanism and cause the deflector bar, if closed, to open.. Then this truck reaches .its `destination the second pin in the bar will pass through the notch 173 and trip the tab 172 to closethe detlector bar. f Y

From` the description above given it. will appear .that the trucks delivered onto the conveyer Cf are dividedb-y the conveyer those trucks having pins in both sides of the central line. being sent to the conveyer J, whilel those having pins on one side only of the central4 line are sent to the conveyer I. TheV trucks sent `to the conveyer I are carried along such conveyer until they reach the deflector mechanism associated with the branch conveyer K to which they 'are intended. YWhen this mechanism is reachedvfthe pin on the truck will pass through the notch 173 in the tab bar 171 and will. actuate the tab bar 172, thus causing the deflector bar 153 associated with suchbranchconveyerto move into the closed positionifit then be open and deflect the trucks onto the branch conveyer. v Y y v Should here be a number of trucks delivered onto the conveyerA G, all intended for the same branch conveyer K, it is necessary that only the first and last trucks of the group be provided with pins. It will benoted that the various mechanisms described remain in the position in which they are set until they y are positively shifted into another position. Consequently a train of trucks yall for the same destination will travel to such destina# tion without any change of mechanism.

Certain of the conveyers K are as shown in 1 arranged in pairs and the destination of the trucks is so determined that those having Vone side open (see Fig. 4) are delivered upon conveyers on which the open sides Willbe readily accessible. Thus refers ring to Fig. l the trucks Whose right sides are open Will be delivered to a left conveyer of any pair of conveyers K and those Whose left x5 sides are open will be delivered to a right conveyer.
